One-dimensional Hubbard-Holstein model with finite range electron-phonon coupling
F. Hébert, Bo Xiao, V. G. Rousseau +2
The Hubbard-Holstein model describes fermions on a discrete lattice, with on-site repulsion between fermions and a coupling to phonons that are localized on sites. Generally, at ha…
Simulations of ultracold bosonic atoms in optical lattices with anharmonic traps
Olivier Gygi, Helmut G. Katzgraber, Matthias Troyer +2
We report results of quantum Monte Carlo simulations in the canonical and the grand-canonical ensemble of the two- and three-dimensional Bose-Hubbard model with quadratic and quart…
Reply to Comment on "Roughness of Interfacial Crack Fronts: Stress-Weighted Percolation in the Damage Zone"
Jean Schmittbuhl, Alex Hansen, G. George Batrouni
This is the reply to a Comment by Alava and Zapperi (cond-mat/0401568) on Schmittbuhl, Hansen and Batrouni, PRL, 90, 045505 (2003).
Supersolids in the Bose-Hubbard Hamiltonian
G. G. Batrouni, R. T. Scalettar, G. T. Zimanyi +1
We use a combination of numeric and analytic techniques to determine the groun d state phase diagram of the Bose--Hubbard Hamiltonian with longer range repulsi ve interactions. At…
